Orfordville, Wis., assignor, by

mesne assignments, to Rockwell Manufacturing Company, Pittsburgh, Pa., a corporation of Pennsylvania Application June 11, 1947, Serial No. 753,874 21 Claims. (01. 242-9) My invention relates to power mechanisms for producing a reciprocating motion, and more particularly to motors of the reciprocating type adapted especially for use with coil winding machines.

The winding of wire, cable, cord, or any such material in layers on a spool or core member is usually accomplished by attaching the material to the spool or core member and rotating the latter while the material is guided thereon by a reciprocating member. If desired, the spool or core member may be both rotated and reciprocated longitudinally relative to a stationary guide to cause the material to be wound in the manner desired. In either case, it will be seen that the strand of material must be inclined relative to the spool or core member to cause the turns to progress along its length. The angle of inclination and the speed of longitudinal movement depend, of course, upon the diameter of the strand and the rate at which the spool or core member is rotated. When the end of one layer is reached, it is necessary that the strand be inclined relative to the spool in theopposite direction so that theturns will follow each other to form the next layer. If there is some delay in reversing the direction at which the strand leads the turns on the piling up of turns at the ends of each layer. It is therefore desirable that there be a rapid longitudinal movement at the beginning of each reciprocation, and then a slower steady movement as the strand is wound upon the spool.

An object of my invention is to provide improved means for positioning wire or stranded material so that it is wound in smooth layers on a spool or core member. Another object is to provide an improved motor of the reciprocating type. Yet another object is to provide a power mechanism including relatively reciprocable cylinder and piston elements, and means for controlling the supply of fluid to said elements for effecting relative reciprocation in an improved manner. Still another object is to provide improved means for actuating a valve mechanism controlling the supply of fluid to a cylinder containing a reciprocable piston. Other objects will appear in the course of the following description.

In the accompanying drawings, in which there is shown for purposes of illustration, one form which my invention may assume in practice:

Fig. 9 is a schematic diagram of a clutch and control means for the machine of Fig. 1.

Referring to the drawings, and more particularly to Fig. 1, it will be noted that I have shown my invention incorporated in a coil winding machine generally designated I. This ma chine comprises a spindle 2 rotatably supported by a framework 3 and driven by a motor 4 contained within a housing 5. The motor is shown herein connected by a belt 6 to a pulley l mounted on a shaft 8 which is connected by a clutch mechanism 9, shortly to be described more in detail, to the spindle 2. It will be understood that the motor may be connected, if desired, by suitable gearing to the shaft 8 instead ofby the belt. Mounted upon the spindle are spools or core members Ill, about which layers of wire are to be wound from reels ll supported by projecting arms I2. As shown herein, a separate reel of wire is provided for each spool, and the wire passes from each reel over a guide member l3 to the spool upon which it is to be wound. The guide members are fixed to a rod I4 which is reciprocably supported by a frame [5 and is operatively connected to my improved mechanism It to be reciprocated thereby in a manner to be shortly described.

The mechanism 16 comprises a guide block l8 supported within the housing 5, as shown in Fig. 1, and having a carriage l9 slidably mounted upon it for movement in a plane parallel to the axis of the spindle 2. Formed integral with the guide block is a dovetail portion 20 fitting into a recess of similar shape in the carriage .for guiding the latter in a path extending longion the plane of the line tudinally of the spindle. Fixed to the carriage for movement therewith is closed at its ends by is a cylinder 2|, which head blocks 22 and 23.

Slideably received within the cylinder, as shown in Fig. 2, is a piston having a piston rod 26 which extends through an opening in the head 22 and is attached by a nut 21, to a member 23 fixed to the guide block 58. Attached to the cylinder head 22, as by Welding, is a member 30 which is adaptedto be'connected to the rod Hi for transmitting motion to the latter. Itwill be noted that a supply of fluid to the cylinder 2| at one side of the piston, while the other:

end of the cylinder is connected to exhaust, will. result in a movement of the cylinder and car-- a valve sleeve't i reciprocably receiving piston:

like valve portions'35, 38 andST-formed-on a valve member 33. The valve portions35, 31 ccoperate with annnular grooves ll-Min the valve sleeve for controlling communication between the latter and passage means to asump, shown in Fig. l. The valve portion 35 cooperates-with an annular groove ed tor controlling communication between the sleeve and a passage means IS-leading to-a pump. 4% driven by a motor 4'! and having its intalre connected to the sump. Opening throughthe' sleeve at opposite sides ofthe groove-Mare passages 58 and 5| whichare connected by conduits 52 and 53, as shown in-Fig. 2, to opposite ends of the cylinder 2!. The ends of the valve member 38 project through opposite ends of the valve casing, andan arm54is connected to the valve memberand is adapted to beactuated by a mechanism 55 for moving the-valve-relative to the casing.

When the arm- 541s actuated to move the valve portions 35, 38, 3'1 to the right in Fig. 2, a liquid, such as oil, is delivered by the pump through passage means edge of the'valve portion 36- to the valve sleeve where it enters thepassage 5i] and is carried by the conduit 52 to the cylinder 2| at the righthand side of the piston 25. The opposite end of the cylinder is connected through the conduit 53, the valve sleeve, the annular groove: ii, and the passage means 43 to the sump. The oil supplied to the oylinder'acts to the right and, since the cylinder, thecarriage l9 and the valve casing 33 are connected together,-the valve sleeve 34 will be moved in the direction in which the valve was displaced until the annular grooves 35, 3E and 3? are'again' covered by their respective valve portions andthe flow of oil relative to the cylinder is cut off. A'displacement of the valve to the left resultsin a movement of the cylinder, the carriage, and.

the valve casing in the opposite direction.

The mechanism 55for actuating. the arm 5% comprises a cylindrical shaped member 56 rotat ably received within-a bore 5'! formed inth'e block l8. An annular member 58 is attached to. the: block by screws 59 and cooperates with a;

flange 60 on the member 58 for holding the latter against longitudinal movement in thev bore 51. Formed in the member .5..are stepped bores 62 and 63, and a shaft :64 extends through the bore 62 and is providedwith anxenlarged; head 56 rotatably received within the .bore63; A. sleeve .shapedmember '68::is .receivedewithinxthe s2 and 43 leading 45 and past the left-hand a move the latter to bore 63 and is keyed at 10 to the member 56 for rotation therewith. Arranged within the bore 53 between the head 66 and the member 68 is a piston ii having a piston rod I2 extending through the sleeve member 68. The adjacent ends of the head and the member 68 8.112 provided with friction surfaces'lil, as shown in Fig. 3, and the piston H is adapted to be moved into engagement with one or the other of these surfaces. A ball bearing '14 is arranged between the inner. end of the bore 63 and the head 66 to form a rotatable end support for the latter.

Connectedto the shaft 64 is a gear 15, and connected to a portion 15 of the member 56 projecting beyond the-block I8 is a gear l'l. Fixed to the spindle 2 of the coil winding machine, asshown in Figs. 1 and 8, is a gear 19 meshing with a gear on a shaft 8| rotatably supported by thehousing 5. Another gear 83 fixed to the shaft 8i, Fig. 2, meshes with the gear 15 and with a gear Monthe shaft-85; rotatably sup ported by the' block l8. Another? geari 86*fixedv tothe shaft 85 meshes with the gear Ti;- Itwv'ill' be seen that the shaft 84' and its head Stews-11 be rotated in one direction through the gears 19, 88, shaft Bland gears83', i 5, whiletthezmem' ber 56 and the member 63. keyed theretoare rotated in the opposite direction" through the: gears 79, 30, shaft 3!, gears 83, 84, shaft-85,

io -and these ports are connected selectively to .a-iliq uid supply or to a sumpby a valve mechanism-r. generally designated 92; To prevent 'anytrap ping of liquid between the piston H iandt'theendi surfaces of the head 55am]. themember 56 ,'thereare provided grooves 93 and 94 m these surfacesas shown in Figs. 2 and 3. It'will be notedialsotthat communication is always provided" between thepiston and the ports 50,9 I through the grooves L 93, 94 and annular grooves 95 in the head 66 and: the member 58'so that operationofthe piston' is assured.

The valve mechanism 92 comprises, as=shown in Figs. 2 and 6,21. housing i Mi connected ftotheblock IS'and containing a valve sleeve. I01 in which piston like portions l02and m3 of a valve member I04 are reciprocably received. Opening through the valve housing and the sleeve [ti 'arepassage means ltfiand It? which are connected 'by"con='- duits I08 and lililto the ports" 38, 94 openin'g into-T the bore 63. Thevalve portions I02 'and lil3 are the valve housing and'provide abutments H4? which limit sliding movements of the valve' to" positions in which itsportions I82 and 'lll3 are-at one side or the other of the passage mea'ns105 and I01. Communicating with the interior of the-" valve sleeve at its mid portion is a passage means H5 which is connected by a conduit llt to the discharge side of the oil pump 46.:- Opening into the valve sleeve near-its ends .areipassage means I I8 and. l I 9 which areconnectedbylconduits5120f r and; l 2 l .to the oilisumprz When the valve member I04 is moved into engagement with the valve housing at its left hand end as viewed in Fig. 6, the supply passage H5 is connected through the passage means I06 and the conduit 08 to the bore 63 at the lefthand side of the piston 1I in Fig. 2. The opposite side of the piston is connected through the conduit I69, passage means I01, valve sleeve IOI, passage means H5, and conduit I2I to the sump. The piston is then moved to the rightinto engage ment with the end of the member 68 so that it is caused to rotate with the latter in one direction. When the valve member I64 is moved into engagement with the opposite end of the valve housing, the supply passage H5 is connected through the passage I51 and the conduit I09 to the righthand side of the piston 1I while the left-hand side of the piston is connected through the conduit I08 and the valve sleeve to the conduit I20 leading to the sump. The piston is then moved into engagement with the head 66 and rotated with the latter in the opposite direction.

In order to move the valve member I 04 into one I or the other of its limiting positions, there are provided adjustable abutments in the form of screws I25 and I26 threaded into bosses I21 formed on the movable carriage I9. An arm I28 fixed to the reduced portion l I I of the valve member is adapted to be engaged by the screws I25 and I26 for effecting longitudinal movement of thepvalve member.

Mounted on a reduced portion I38 of the piston rod 12, as shown in Figs. 2 and 7, is a sleeveshaped member I3I which is clamped between a shoulder I32 on the rod and a washer I33 by a nut I34 threaded on the end of the rod. Formed on the member I3I are threads I36, which are adapted to be engaged by a pointed member I31 carried by the arm 54. As the member I8I is rotated, the pointed member I31 follows along the threads I36 and causes the arm 54 to move and position the valve member 36 within the sleeve 34. When the piston II is moved between the head 66 and the member 68, the member I 3| is moved longitudinally and carries the pointed member I31 with it to eifect an adjustment of the valve member 38. The space provided between the head 66 and the member 68 may be adjusted by a cap I40 threaded on the cylindrical member 56 and engaging the member 68 for positioning the latter. As the cap is threaded on to the member 56, the member 68 is forced toward the head 66 to reduce the space between them. Rotation of the cap in the opposite direction provides a clearance between the cap and the member 68. If oil is then supplied to the piston H for moving it into engagement with the member 68, the latter is forced against the cap, thereby providing a larger space for movement of the piston.

The clutch mechanism 6 for transmitting power from the shaft 8 to the spindle 2 comprises, as shown in Fig. 9, a casing I45 supported by any suitable means within the housing 5 and having a bore I46 in which an enlarged head portion I41 on the shaft 8 is rotatably received. The spindle 2 extends into the casing to a point adjacent the head portion and has a piston I49 slideably keyed thereon for movement into engagement with either the head portion I51 or a braking member I50 fixed to the casing. Passages I 5| and I52 open through the casing at opposite sides of the piston and communicate with annular grooves I53 and I54 which are connected by grooves I55 and I56 with spaces at the ends of thepiston.

The passages I5I and I52 are connected through conduits I58, I59 and a valve mechanism I60 to either a supply conduit I6I or to exhaust conduits I62, I63, the supply conduit being connected through a valve I64, Fig. 1, to the pump 46, and

the exhaust conduits communicating with thesump.

The valve mechanism I60 is shown herein as comprising valve pistons I65 and I66 slideably received in a valve bore I61 and connected to a plunger I60 of a solenoid I69. When the solenoid is energized, the valve pistons are moved to the positions shown in Fig. 9 for connecting conduits I58 and I59 respectively to the exhaust conduit I63 and the supply conduit I6I. On deenergizing the solenoid, the valve pistons move to positions connecting conduits I58 to the supply conduit and connecting conduit I59 to the exhaust conduit I62. The winding of the solenoid is connected at its ends to conductor I1I, I12 leading to adjustable contacts I14, I15 of a clock mechanism I16 driven by suitable-means, not shown, from the spindle 2. The clock mechanism is provided with two arms I16, I19 pivotally supported on a common axis and driven so that one of the arms swings through 360 for a predetermined number of turns of the spindle, while the other arm moves between two adjacent figures, as shown on Fig. 1. are arranged to be contacted by the arms and connected electrically by the latter as they swing about their pivot. It will be seen that one of the contacts will be connected by the faster moving arm each time it swings around, but both contacts will be made only when a. predetermined number of turns of the spindle has been completed. A source of power, such as a battery I80, energizes the solenoid through the arms I16, I19 when they engage the contacts. Suitable means may be provided for moving both arms to a zero position when the winding of coils begins.

The winding of coils is accomplished by connecting the wires to the core members I0 on the spindle and adjusting the arms of the clock mechanism to their zero positions. The solenoid is deenergized at this time, and the valve pistons are in positions connecting conduit I58 to supply and conduit I50 to the sump. The valve I64 may then be opened to supply oil through conduit I58 to the piston I49 for moving it against the head I41 driven by the motor 4. The

spindle is then caused to rotate, and by reason of the gear 19 on the spindle meshing with the gear on the shaft 6I, a rotation of the shaft 56 in opposite directions is v I3 is in a position at this turn the member I3I in a direction to cause the pointed member I31 to travel along it and position the valve member 36 for supplying .oil to the cylinder 2| so that the latter moves and carries the guide members in a manner to eifecta smooth winding of wire on the core members in one direction. It will be seen that movement of the member I31 along the member I 3I continues until the carriage reaches a position where one of the adjustable abutments The contacts The valve' supply oil I I25, I26 engages the arm I28 and moves the valve I04 to a position for'supplying oil through conduit I09 to the pisem na 7 ton: Ti and'flfbrcing the-latter against the rota't head lilii- T-helongitudinal movement-of th'e piston is -suoh" as to position the valve-3'8- at the opposite sides of itsfluid passages a sufficient distance to effect a rapid i movement of the carriage in the opposite direction until theguide' members direct the wire for turns following eachother-along the core towardits other-end.- The engagement of the pistonl-l with the: head lsfi' causes it torotate in a direction'to' feed the mem'-' ber l3-1'along the member I3! and sheet a continuousmovement of the carriage for positionine theig-uide members to obtain a=smooth layer ofwire' in the opposite direction. It Willbe seen that the movement of the-piston between them'ernber 68- and the head 56 produces rapid movement of the carriage inthe opposite'direc tionas-a'new layer of wire isstarted, thus pre- Venti-ng the piling up of turns at the end of the spool; The distance of 'travel by the carriage in eacli direction may be easily adjusted by changing the positionsof theabutments I25;- I28:- Thetr'a'velof the piston between the member' fiii and the head fili' may be adjusted by rotating the cap- I40, and th speed of movement of the ear riage while'turns are made on the core members is det'er'mined by the threads on the member i3'i which -may easily be replaced by another with threads of a-difierent pitch, when desired. When therequired numberof turns have been made, the" arms ofthe clock mechanism engage the contacts I14} l'l5and' energize the solenoid, V25! for-positioning the valve Hill to supply oil to conduit l59 and connect conduit N38 to the sump; Pistonl49 is then moved to the left inFig 9 against the stationary member 158, which causes the spindle to be quickly stopped.

While there isshown in this application one formwhich my invention may assume in practice, it will be understood that it may be modified and embodiedin various other forms without departing from its spirit or thescope ofthe appendedclaims.
